Examples how to use ZOHO API in VS2005 or Delphi?

Hello,

does anyone know information sources how to use the ZOHO API in VisualStudio or Delphi.

My special questions are:

* What do i need to install in VS or Delphi to get started?
* How does the application authenticate at the server?
* How do i send the requests to the server?

The API documentation lists only the availabel methods but does not answer "beginner" questions like these

Thanks in advance,
Ralf
